How are diamonds created in the laboratory?
There are two ways to get diamonds in the laboratory:
HPHT is a method that uses high pressure and temperature. Three types of press layout are used - a belt press, a cube press and a press with a split sphere. The latter is considered the most perfect to date. It was developed by Russian scientists in 1989-1991.
CVD stands for chemical vapor deposition. In this method, diamond grows by depositing carbon onto a seed of a hydrogen-carbon gas mixture. Unlike the HPHT method, it does not require high pressure.

Both are real!
Both grown and mined diamonds are composed of a crystalline carbon structure. From their chemical composition to their appearance, they are exactly the same. So what's the difference? Their impact on the world. Diamonds mined from the earth are not only more expensive, but also more expensive for the world. In order to extract 1 diamond weighing 1 carat, it is necessary to move 50 tons of earth. There are tens of thousands of depleted and abandoned diamond mines around the world.

Simple chemistry
The difference between LAB GROWN and artificial diamonds lies in the composition. Simulants such as zirconia, white sapphire and moissanite are made up of a proprietary blend of elements that mimic the appearance, weight and wear of diamond but differ in chemical composition.
